"Naturally occurring climate change"
LOL. With the largest spike in temperatures in recorded history? All in the matter of a few years? Give me a break.
Was it Co2 produced by man that put an end to the mini ice age?
Or was it a natural variation in the earth's temperature.
I'm not saying global warming doesn't exist but I'm not convinced that it does either.
The earth has warmed and cooled at various times in history. However, never at such a massively quick rate absent an epic catastrophe such as a Yellowstone volcano eruption, a massive meteor striking the earth and other similar events. There hasn't been such an event in the last 50 years. The difference is that explosion of carbon dioxide and other pollutants into the atmosphere. So what else is it? Especially when considering that when global warming is modeled scientifically, the only factor that matches nearly identically is the one based on man-caused global warming.
I'll also add that most major US companies accept that global warming is a man-made phenomenon. Some large companies such as General Electric and DuPont actually endorse federal regulation as a method to combat this problem.

The Younger Dryas saw a rapid return to glacial conditions in the higher latitudes of the Northern Hemisphere between 12,900 – 11,500 years before present (BP) in sharp contrast to the warming of the preceding interstadial deglaciation. The transitions each occurred over a period of a decade or so .Thermally fractionated nitrogen and argon isotope data from Greenland ice core GISP2 indicates that the summit of Greenland was ~15 °C colder than today during the Younger Dryas . In the UK, coleopteran (fossil beetle) evidence suggests mean annual temperature dropped to approximately -5 °C , and periglacial conditions prevailed in lowland areas, while icefields and glaciers formed in upland areas . Nothing of the size, extent, or rapidity of this period of abrupt climate change has been experienced since .
Measurements of oxygen isotopes from the GISP2 ice core suggest the ending of the Younger Dryas took place over just 40 - 50 years in three discrete steps, each lasting five years. Other proxy data, such as dust concentration, and snow accumulation, suggest an even more rapid transition, requiring a ~7 °C warming in just a few years .
The end of the Younger Dryas has been dated to around 9600 BC (11550 calendar years BP, occurring at 10000 radiocarbon years BP, a "radiocarbon plateau") by a variety of methods, with mostly consistent results:
- - - - - - - -
So within a decade (or less) the mean temperature rose 7 degrees celsius. And there weren't suvs back then, so . . .
And in fact the more you look in to it the last 10000 years or so of relative stability is actually the exception, rather than the rule. If you go to seattle and manage to get a week straight of sunny blue skies, then come back later to find it raining it would appear to you that things really went downhill, when in reality you just happened to hit a freakish pleasant spell.

There weren't SUV's in the 90's?

The exception's surely had something to do with our expansion.
Here are a few of many differences between the Earth now and in the centuries/millenia ago that these last changes happened-
Now there are over 600 million motor vehicles
Now there are over 6,600,000,000 people (a few with modern Computation Mechanisms!)
Now there are over 3,000 power plants.
Now the extinction of many species of plants and animals depends on human activity from now on.
China and the US each emit over 5,000,000,000,000 metric tons of carbon dioxide (into thin air) every year and the number's rising.
I could spend a lot more time listing a lot more changes but there is no point, you Know what you Know and your mind will never change about what we can do.
Ignore this, like the questions I asked you.
(and I can see this is a JOKE ballot, I apologize for posting facts, not jokes. Some things are important enough to take the bad karma for)

aya; 9600 BC, would you say at that time the earths temperature was entirely dictated by mans actions, or was it more "natural" back then?
Jyl, so in your opinion, correlation proves causation? There are also far more telemarketers today than 2000 years ago, clearly telemarketers cause global warming.
good answer, genius

Herzog, let me make it clear for you. In NO time in history has there been such a rapid increase in temperatures in such a shot time in history without some catastrophic event. You quote an event that was about global cooling - this is a bit different than global warming in case you haven't noticed. You also selectively choose which information to quote. The younger dyas occurred as the ice age was ending. It was likely the result of a sudden influx of cold water into the ocean which caused a change to the Atlantic Ocean's conveyor circulation pattern. What you also conveniently forget/omit is that the earth was in a prolonged warming period lasting hundreds to thousands of years. Temporary abrupt downturns of a temperature would have been expected with such a large number of glaciers and ice melting quickly. There are no glaciers in Pennsylvania today that are melting. The events are completely dissimilar and you know this.
I would suggest that you go back to the library or use a service such as Lexis/Nexis to research further. If you were to do this you would find the consensus opinion to be what I stated.
You use dissimilar events to try to make a point. That is intellectually dishonest. The model used to explain the younger dryas event is not at all relevant to today's global warming. Using the younger dyas model does not fit with what is happening today. Using today's global warming model does not fit the younger dryas event. Using the global warming model for the massive increase in pollutants each year continues to match what it has predicted would happen.
So, sure go ahead and burn fossil fuels, run you polluting SUVs, let China use highly polluting coal to power the factories. Hey!! None of these things could possibly have ANYTHING at all to do with global warming. Screw any regulations. Might as well not worry about it. Mankind has nothing to do with the most rapid increase in temperatures.
Keep your head in the sand herzog.
^Kind of proves my point, that people aren't reacting civilly to this and instead resort to name calling and personal attacks.
You've called ME things and attacked me a few times lately.
And ignored my questions when they stumped you.
What are You proving?

and your answer there was nothing to do with the issue and the facts stated.
I've done a lot of looking around lately at what climate scientists are saying, thanks you one of your good B&W buddies I've learned a lot more about what almost all scientists are agreeing on.

'You've called ME things and attacked me a few times lately.

Perhaps I have been a little short with you lately. If so I apologize. Let's just take a break on the whole global warming thing (since it seems to provoke fights) for a little while.
